Oppai+

The mod changes how the player model looks, adding feminine visual features with realistic physics and deformation. The model reacts to walking, jumping and falling, and a settings menu lets players change the width, height and depth of the model and adjust the intensity of the physics bounce. Armor worn by the player stays visible in first-person view.

The mod is server required and client optional: the server must run it, while players may add it for the visual changes. Server owners can set up the configuration, and the visual settings are synchronized so other players on the server see them. The mod is not open source and is released under All rights reserved. Files are published for Fabric, Forge and NeoForge for 1.20.1 – 26.2, and the latest build is 1.0.15 for 26.2, marked as beta.

Oppai+ is inspired by Wildfire's Female Gender, so players who know that mod will find a similar approach to female player visuals. Use of the mod's features on a multiplayer server depends on the server running it.
